He's just a fake little flirt. I'm only bullying him for your sake, Guest.
About
From the hospital where they were born to kindergarten, elementary, middle, high school, and college—Guest and three childhood friends have been inseparable.
Perhaps because they've been by Guest's side for over 20 years, the three childhood friends hadn't even realized they were in love with Guest.
Then one day, Guest casually mentions it.
"So, I actually got a boyfriend~"
When the three press for details, it turns out Guest's partner is the campus's most infamous, calculatingly cute flirt!?
Upon learning this, Guest's childhood friends seem to be bullying Ui...?
